Specification of Letters Patent.

Patented Dec. 22, 1914.

Original application filed September 27, 1912, Serial No. 722,604.Divided and this application filed. January To all whom it may concernBe it known that I, JOHANNES SURMANN, a subject of the German Emperor,residing at llolzhafen, Bremen, Germany, have invented certain new anduseful Improvements in Collapsible Packings, of which the following is aspecification.

This invention relates to collapsible packing wherein strips of suitablematerial, for instance corrugated cardboard, are arranged crosswise andare bent up to form the box.

The invention of the present application, which is a division of myapplication Serial No. 722604, has for object to provide an improvedpacking wherein no fastening means such as rivets, slits, flaps oradhesive are necessary, the packing being held together when erectedsolely by friction.

The packing is especially suitable for inclosing a spherical or ovoidarticle.

According to this invention the improved box is composed of two stripseach being adapted to be bent transversely to form five full sizepanels, so that when folded together and built up to form the box theend panels overlap and are clamped between the contents of the box andthe wall of same, thus securing the box from unintentional opening.

The invention is illustrated in the accompanying drawing which shows aperspective view of a partly erected box.

As shown, the strip (Z e 5 0 elf, is bent to form a cubical orrectangularly prismatic shell the end panels (Z 03 of which overlap. Oneend panel d of the second strip is then inserted in the interior SerialNo. 743,436.

of the shell formed by the first strip against panel Z2 The rest of thissecond strip is folded around, and the other panel (Z inserted under thepanel 6 Having now described my invention what I claim as new and desireto secure by Letters Patent is l. A collapsible packing composed of twolive paneled strips arranged crosswise to each other, each strip havingend panels of full size, and overlapping each other when the strips arebent up to form a rectangular shell, the overlapping panels of one stripbeing in each case covered by the middle panel of the other strip, andthe packing being held together solely by friction of the overlappingend panels held between the inclosed article and the outer middle panel.

2. A. collapsible packing suitable for spherical articles composed oftwo identical five paneled strips, each panel being of equal size andsquare, the end panels of each strip overlapping each other when thestrips are bent up to form rectangular shells, the overlapping panels ofone strip being in each case covered by the middle panel of the otherstrip, and the packing being held together solely by friction of theoverlapping end panels held between the inclosed article and the outermiddle panel.

In testimony whereof I affix my signature in presence of two witnesses.
